End is in the Shaft groove.During piping expanded by heating, position of the fulcrum is all subject to about in tri- direction displacements of the lines of X, Y, Z
Beam；But, in the horizontal plane, pipeline can be rotated centered on vertical rotating shaft, do not limit the angular displacement in RZ directions, so as to can
To discharge section of tubing thermal stress.
In above-mentioned technical proposal, support frame as described above is square；The cross-brace frame is rectangle, and the upper rotation
Axial trough is located at the cross-brace frame center.Make overall structure stress balance.
In above-mentioned technical proposal, the gripper shoe is in cruciform shape, and the Shaft groove is located at the support
Plate decussation center.Make overall structure stress balance.
In above-mentioned technical proposal, the pipe clamp and pipeline adopt Type of Welding or adopt bolt pipe clamp and fixture block spacing.
It is easily installed, dismantle and keeps in repair.
In above-mentioned technical proposal, there is poly- four ethylene pad to be located in the middle of the rotary shaft and the rotation axial trough.Reduce
Frictional force between rotary shaft and rotation axial trough, and reduce abrasion.
In above-mentioned technical proposal, the rotary shaft and pipeline produce rotation centered on the axle perpendicular to the rotary shaft
Turn, and thermal deformation angle angular range is -90 DEG C～90 DEG C.It is easy to rotary shaft and pipeline to follow thermal expansion pipeline to rotate freely
Motion.
This utility model has the advantage that：
(1) provide a kind of brand-new pipeline constraint type；
(2) increase rotary shaft on pipe clamp, pipeline is under heating status, it is allowed to the free angular displacement of a certain plane；
